What is AI2SQL?
AI2SQL is an AI SQL assistant that connects to your database (PostgreSQL, MySQL, SQL Server, Oracle, Snowflake, BigQuery, Redshift, MongoDB, SQLite, Firebird) and reads its schema. It builds a semantic layer from tables, joins and business terms, so generated queries use your real column names and the correct dialect.
You can describe the result you want in plain English and get SQL back, or paste an existing query to have it explained, optimized, fixed or formatted. Queries can be run against a read-only connection and the rows shown on the page. A governed MCP endpoint and REST API let agents such as Claude or Cursor run read-only queries, with logging and per-agent keys. A desktop Connector runs locally so credentials stay on your machine.
